He also doesn't take time to think about the fact that he is willingly working with someone he doesn't know from Adam to get out of this f-ing laboratory. He really HATED being locked up. Then, spotting a heavy, fairly tall desk he heads that way silently.]

Got any tools on you, to get the vent open?

[Without waiting for an answer he heaves on the desk, digging in and shoving it bodily across the floor till it sits just below the vent.]

Might be tall enough [he rumbles].
